Run long autonomous builds through a GAN-style Generator/Evaluator harness

Epsilla·medium signal

Anthropic's multi-agent harness for multi-hour autonomous development splits work across distinct planner, generator, and skeptical evaluator agents — an architecture explicitly inspired by GANs, where the evaluator's adversarial feedback loop keeps output coherent over long sessions instead of drifting. The practical takeaway for builders: don't let one agent both produce and judge its own work; stand up a separate evaluator agent (different prompt, possibly different model) whose only job is to challenge the generator before changes are accepted.
